inertia governor

unnecessary explanations. Do things first! Delay is a waste of life. Procrastination is common in people's daily life. If you record a day, you will be surprised to find that delay is consuming our lives unconsciously. Delay is due to the inertia of people. Whenever we have to pay for work or make a choice, we will always find some excuses for ourselves to comfort ourselves, I always want to make myself more relaxed and comfortable. Some people can q

Last time, the implementation of the elementary particle swarm algorithm was discussed, and the C language code was given. This article mainly explains an important parameter affecting particle swarm optimization---w. We have already said that the core of the particle swarm algorithm is two formulas:Vid (k+1) =w*vid (k) +c1*r1* (Pid (k)-xid (k)) +c2*r2* (PGD (k)-xid (k))Xid (k+1) = Xid (k) + Vid (k+1)The red w is the parameter that we are going to discuss this time. Before W is unchanged (by def

with the heat sink high-frequency collision, if the fan and heatsink then stable, the impact of the vibration noise can be greatly reduced. For example, the high-speed rotating CPU fan held in the hand, the noise is far less than fixed on the heatsink, this is because the soft hands absorb a lot of vibration. By this principle, the noise generated by the vibration of the fan and heatsink can be effectively reduced by adding a 1~2 mm thick cushion piece (such as leather, rubber) between the fan

Today write here how to control the speed of the DC motor with a single chip microcomputer. DC Governor is to adjust the speed of the DC motor equipment, the upper and the AC power connection, the lower and DC motor connection, DC

pool. Different resource pools are bound to different workgroup workloads, which enables resource isolation for each workgroup load.3. ClassifierThe classifier provides a set of rules that divide the workload of the workgroup, based on which SQL Server classifies the client's requests into multiple workgroups.For example, with the user name of SQL Server as a classifier, all requests from a user are divided into workgroup load 1, and all requests from B users are divided into workgroup load 2.

the ability to allocate resources as required by users. Next we will introduce this function. The SQL Server Resource Controller is divided into three parts: resource pool, load group, and classifier function. The resource pool allows us to divide resources (such as CPU and Memory) into different carriers, the load group carries the load and These loads are mapped to the resource pool, and the classifier function maps different sessions to different load groups. Resource Pool: 08 provides

closer to the worm. The other babies are almost all gathered to the small blue side. In the end, everyone ate the worm.three, particle swarm algorithm3.1 Story AnalysisThe story of bird feeding is precisely the reason why this particle swarm algorithm exists. So, if you want to get a better understanding of particle swarm optimization, we're going to analyze the story of baby bird predation. First of all, we analyze and analyze the state of the birds ' movements, that is, how the baby birds dec

right sides are cliffs, the saddle point is shaped like a saddle, two in one direction, two in the other direction, and the central area is an almost horizontal flat.Why is SGD most afraid of encountering these two types of terrain? In the valley, the exact gradient direction is along the Hill Road downward, a slight deviation will hit the mountain wall, and SGD rough gradient estimate makes it bounce back and forth between the two mountains, not along the direction of the hill to rapidly decli

poor ?......Looking at these various people, I often think of what the boss said. It feels like truth. Life is equal. This equality is not only reflected in human rights, but also in other aspects. For example, people both have an animal instinct and a rational one. According to the animal instinct, people will unconsciously greedy for the physical enjoyment of the senses, such as laziness, freedom, and self-interest. It is not "bad" to say that they play for a while or sleep for a while ", it

In Android development, this situation is often encountered.ProgramWhen running, you can dynamically decide whether to display a widget or layout based on the current conditions. In this case, you can use the inert control viewstub to conveniently complete this function. The viewstub is a lightweight view that enables Dynamic Layout loading. The viewstub object is an invisible, zero-size view, and is dynamically loaded as needed when the program is running. Only when the viewstub object is set

"pseudo recursion ",What do you mean? Since we can optimize it, for most functional programming language compilers, they also provide optimization for tail recursion, so that tail recursion can be optimized into the form of loop iteration, this prevents stack overflow. 12. Evaluate inertia and Parallelism The first time I came into contact with the concept of inertia evaluation, I think it is also t

. Therefore, you can use the direct conversion defined by the ouarla corner to directly generate inertia-the general form of the object rotation matrix: MInertia --> Object =HPB H,P,BThey are the rotation matrices of heading, pitch, and bank. They rotate around y, X, and Z axes respectively. Only rotating the "coordinate space" is the exact opposite operation of rotating the "point. We can imagine that the rotation time point remains unchanged in the

Simulating the physical characteristics of Gameobject objects in the real world (gravity, resistance, mass, speed) Assignment codes for Rigidbody object properties are usually placed in the Onfixedupdate method of the script Collisondetectionmode Properties--Collision detection mode There are 3 types of collision detection modes for rigid bodies discrete--Static discrete detection mode continuous--static continuous monitoring mode, generally used in high-speed moving rigid bod

always smiled and did not say anything related to politics. After returning, he reported Cao, saying that Zhou Yu was ambitious and could not shake his speech. The romance describes Jiang Gan's failure to describe the client, but instead, he plans to make it possible for Cao to mistakenly kill Cai Yu and Zhang Yun. This is not historical. 11 Zhang Fei's anger, dingdu mail? Zhang Fei's anger, dingdu mail? In fact, the real culprit is Liu Bei. Let's take a look at the description of the official

a hook to truly reproduce the "QQ tail virus" technology. First I make a brief introduction to the hook, and friends who are already familiar with the hooks can skip this paragraph. The so-called Win32 hook is not an artificial arm of the captain of the hook, but a piece of procedure that can be used to monitor, detect, and perform certain functions in a particular message in the system. For example, your program is the emperor, the Windows system as the go
